Massachusetts could become the first state in the country to ban prop bets entirely — and starting today, June 1, the state is already forcing sportsbooks to tell you when they limit your account. The Massachusetts sports betting bill June 2026 could make sweeping changes. Bill S.302, the so-called “Bettor Health Act,” passed a key committee vote 5-0 and is now sitting in Senate Ways and Means. If it becomes law, your same-game parlays, player props, and in-game live bets are gone. Dead. Wiped off every Massachusetts sportsbook.
But here’s where it gets real dirty. DraftKings — headquartered right there in Boston — just dumped $19.5 million into a super PAC called “Win For America” and has been pouring cash directly into the pockets of the two lawmakers who control whether this bill lives or dies.
We’re watching the biggest fight between a state government and the sports betting industry play out in real time. And Massachusetts bettors are caught in the middle.

Massachusetts Sports Betting Bill June 2026: What Is the Bettor Health Act?
The Bettor Health Act (S.302) would gut the Massachusetts sports betting market as you know it. Filed by Sen. John Keenan (D-Norfolk/Plymouth), this sports betting bill cleared the Joint Committee on Economic Development and Emerging Technologies with a unanimous 5-0 vote and now heads to Senate Ways and Means.
Here’s what S.302 would do if it passes:
- Tax rate jumps from 20% to 51% — matching New York as the highest in the nation
- Complete ban on prop bets — no player props, no micro-bets, nothing
- Complete ban on in-game betting — live wagering goes away entirely
- Advertising ban during televised sporting events
- Daily wager cap of $1,000 without an affordability check
- Monthly cap of $10,000 before operators must verify you can afford it
- Wagers limited to 15% of your bank account balance
- Bonus and promo offers classified as deceptive practices
- $2 million annually for problem gambling (doubled from $1M)
Keenan isn’t some anti-gambling crusader who never wanted betting in the first place. He voted FOR legalization in 2022. Then the ads started. Then constituents called about family members losing everything. He publicly apologized last year for his vote and filed this bill.
“I can’t stand the idea of moneyed interests pushing products they know are addictive upon people,” Keenan told WBUR.
I’ve been covering state legislation for years, and I’ve never seen a senator apologize for a vote like that. It tells you something about how bad the situation has gotten on the ground in Massachusetts.
How Is DraftKings Fighting Back Against This Bill?
DraftKings isn’t taking this lying down. Not even close. The Boston-based company has gone full scorched-earth.
Here’s the money trail we’ve been tracking:
The $43 million super PAC: DraftKings, FanDuel, and Fanatics created “Win For America,” a federal super PAC that’s been spending in statehouse races across 11+ states. DraftKings alone put in $19.5 million — nearly half the total war chest. The PAC creates smaller front groups with names like “American Conservatives Fund” and “American Future” to run attack ads against lawmakers who push for regulation.
Direct Beacon Hill donations: Over four days in January, DraftKings executives and their families donated $19,800 to Rep. Aaron Michlewitz, the chair of House Ways and Means — the exact committee that will decide if this bill gets a House vote. During the same period, DraftKings donated $17,750 to House Speaker Ron Mariano.
That’s roughly a third of all the money Mariano raised this year. From one company.
DraftKings CEO Jason Robins told investors on an earnings call this month that the company is “experimenting” with the super PAC strategy. “We’re going to try that strategy out for this election cycle, see how it goes,” he said.
Experimenting. With democracy. Cool.
We’ve seen the same playbook in Ohio, where a DraftKings-backed PAC targeted a statehouse candidate who lost her primary after the group spent against her. In Illinois, $196,000 in attack ads torpedoed a progressive candidate in a two-and-a-half week blitz. That’s more than the candidate spent in nine months of campaigning.
Massachusetts Sports Betting Bill June 2026: New Sportsbook Limitation Rules Explained
Starting today — literally today, June 1 — Massachusetts becomes the first state in the country to require sportsbooks to notify you when they limit your account. The Massachusetts Gaming Commission passed this rule back in February, and it kicks in right now.
Under the new rule:
- Sportsbooks must notify you within 48 hours of imposing a limitation
- The notice must explain what was limited (max bet size, market access, etc.)
- Operators must provide a reason for the limitation
- Records must be kept and reported to the Gaming Commission
Sharp bettors know the deal. You win too much, the book limits you. It’s been happening forever with zero transparency. Massachusetts just ripped that curtain open.
This is separate from S.302 but part of the same momentum. The Gaming Commission is tightening the screws from the regulatory side while Keenan pushes legislation from the Senate side.
Is Sports Betting Still Legal in Massachusetts Right Now?
Yes. Full stop. As of June 2026, sports betting remains fully legal and operational in Massachusetts. Retail sportsbooks launched in January 2023, and mobile sports betting went live in March 2023.
Right now, you can bet on everything — game lines, props, parlays, live bets, futures. All legal. All available on your phone.
S.302 hasn’t passed yet. The session deadline is July, and the bill still needs to clear Senate Ways and Means, pass the full Senate, pass the House, and get signed by the governor. That’s a lot of hurdles in roughly one month.
But the limitation notice rule? That’s real. That’s today. If a sportsbook limits you starting June 1, they have to tell you why.
How the Massachusetts Sports Betting Bill June 2026 Compares to Other State Regulations
Massachusetts isn’t alone in the backlash, but it’s leading the charge.
No state has successfully banned all prop bets. Colorado came closest but the industry lobbied the ban out. Louisiana tried and failed. Massachusetts would be first — and the entire industry knows it.
That’s why DraftKings is throwing $43 million at this fight. As one analyst told WBUR, this bill “would set a nasty precedent” if it passes. Every other state considering reform would use Massachusetts as the template.
This growing legal and regulatory conflict around betting innovation is also being discussed in detail in other states, including in relation to prediction markets and their future regulation, as explored in this analysis of Massachusetts prediction markets under pressure — massachusetts prediction markets under fire in 2026.
What Happens Next for Massachusetts Bettors?
The clock is running. Massachusetts’ legislative session ends in July. S.302 must clear all remaining hurdles before then or it dies.
Key dates and next steps:
- Senate Ways and Means hearing — not yet scheduled, but expected in June
- Full Senate vote — needed before session ends
- House action — requires Speaker Mariano and Chairman Michlewitz (the DraftKings donation recipients) to allow a vote
- Governor Healey’s position — unclear, but DraftKings donated $50,000 to a nonprofit aligned with Healey last September
The honest take: I think this bill is a long shot to pass in its current form this session. The House leadership has DraftKings money in their pockets, the session window is tight, and no state has successfully pulled off a prop bet ban yet. But the 5-0 committee vote shows real momentum. Even if S.302 dies in July, a version of it comes back in the next session — and the industry knows it.
For bettors who want to keep their options open regardless of what Massachusetts does, offshore books like Bovada, BetUS, and MyBookie operate outside state jurisdiction. These platforms still offer props, in-game betting, and everything Massachusetts might ban. We’ve been using Bovada and MyBookie for years and they’ve been reliable, though you obviously lose the state-regulated consumer protections.

Frequently Asked Questions
Yes — right now, today, prop bets are fully legal in Massachusetts. S.302 has not passed. You can bet player props, same-game parlays, and in-game wagers on every licensed sportsbook in the state. That changes only if S.302 becomes law.
If a Massachusetts sportsbook limits your account — reduces your max bet, restricts which markets you can access, or caps your winnings — they now have 48 hours to tell you. You’ll get a notice explaining what changed and why. This rule took effect June 1, 2026.
Almost certainly. When New York enacted a 51% tax, operators responded by offering worse odds and fewer promotions. The math is simple: if a sportsbook keeps less money, they compensate by taking more from bettors. Expect thinner lines and fewer bonus offers if S.302 passes.
Offshore sportsbooks like Bovada, BetOnline, MyBookie, and BetUS are not subject to Massachusetts law and would continue offering prop bets, in-game wagering, and everything else regardless of state regulations.
